Would a vacuum chamber (a tube with no air in it) float on water?

Question

Could I have have a reason as well?

Answer 1

If anyone answers 'yes', they are wrong.
If anyone answers 'no', they are wrong.

Floating versus sinking is to do with density. Density is the mass per unit volume. Something will sink if it is more dense than the liquid, or float if it is less dense than the liquid.

In this example, the liquid is water. The density of water is approximately 1kg/m^3 (thats one kilogram per metre cubed).
The density of the vacuum chamber depends on its size and weight. The inside has no mass (as it is a vacuum), but the actual container has mass. So if you take the mass of the container, and divide it by the volume of the container, you will find its density. If it is less than 1kg/m^3 it will float, if not it will sink.

So, the next question I can see leading on from my answer is "What if it's got air in it instead?" Well, air does have mass, although it isn't very much. So a container which just floats if it contains a vacuum will sink if it contains air instead.

Answer 2

If a type of plastic will float with ends open then it would float sealed, vacuum or no vacuum. However, if the tube is metal and ends left open, it would sink. If, however, the metal tube is sealed with air inside it must certainly float-so long as it is not too heavy. If there is no air inside then there is nothing to make it buoyant and it would sink. This idea was used in Newcomen's engine where a volume of steam would cause a piston to rise in its chamber then fall when the steam condensed, as steam leaves a vacuum when it cools, (or condenses), back into water.

Answer 3

No. The water became frigid, somebody on the scene later that night curiously suggested it became 28 ranges Fahrenheit (-2 C), meaning the only reason it wasn't frozen became via saline content textile of the seawater. lots of the human beings who ended up interior the water died interior of an hour of being in it. None survived till the rescue deliver arrived except they controlled to get into between the boats. interior the component to the north Atlantic the place the catastrophe got here approximately, circumstances are nevertheless wintry climate-like in mid-April, that's one in all the motives there became a great field of icebergs that had floated down from the Arctic areas. the human beings had no risk to stay to tell the story except they reached the lifeboats. If it had befell in August, it would have been a various tale, yet in August, the huge not at all might have encountered an iceberg there, besides.

Answer 4

As far as I'm aware, a container that can withstand the pressure of pure vacuum pulling at it would have to be very, very strong therefore heavy. So, the container might sink, depending on the material you make it out of.

Answer 5

it eintirely depends on the weight of the tube itself in relation to the water it is in. If the tube has a lower density then the water it is in they yes.

Answer 6

It kind of depends on the DENSITY of the object concerned. More the density the object will sink and vice versa.

Answer 7

Yes.
For anything to float (Archimedes Principle) it must displace more weight of water than it weighs it self. I.E. It must be lighter than the water is displaces. Therefore the air inside will have no influence on its buoyancy.

Answer 8

I depends on the weight of the vessle relative to it's volume.

Answer 9

probably depends on what the tube is made of, but i would guess at no. I'm not sure why at this time

Answer 10

No the container would collapse and sink
